3Com/H3C DAC and Virtual Connect-Flex10 connectivity

[chuckk281]

Yee was looking to get advice on which DAC cables to use:

***************************

Hi all,

Can I know if the 3COM DAC will work with Flex10?

Can’t seem to find any matrix table except for Procurve ones…

*****************************

Richard chimed in:

*****************************

This cable is not listed in the Quick Specs for the flex-10 module (http://h18004.www1.hp.com/products/quickspecs/13127_na/13127_na.html) but there is a note that says:

NOTE: In addition to the supported HP and non-HP Copper Twinax and Active Copper SFP+ cables above, Virtual Connect provides "allowed" connections using third party cables that meet the following criteria: connector=copper pigtail; transceiver code=active cable or passive cable; speed >10Gb; length between 1m and 7m, inclusive. All "allowed" DACs are connected and logged. Prior to requesting support from HP, a DAC from the supported list above must be used to verify a cable issue is not involved.

Hope that helps

Hiro also had some actual experience:

Hi Yee,

Do you mean H3C DAC cable?

We recently tested in Japan to connect VC Flex-10 and A5820 using H3C DAC cable and it did not link up...

VC firmware is 3.15.

Any other input or comments?

So then Yee asked if the oposite was true:

**********************

So is the reverse true? An ISS DAC will also not work on a 3Com switch?

Hi Yee,

In our Proof-of-Concept (PoC), it seems no problem to use ISS DAC although A5820 output warning ” The transceiver is UNKNOWN..”.
